......And in addition, could it be that the pelvis of female pterosaurs did
expand during egg - laying? Surely the presence of cartilage connections
could point to that.

How many Haopterus specimens are known with intact pelvises? (an honest,
unbaited question--I truly do not know the answer to this) What do we know
about the size range of this critter?

How much has the egg's diameter been affected by crushing? It probably
hasn't been expanded from 10 mm to 41 mm, but surely there has been some
alteration.
